-===== Metadata =====
+===== Document Metadata =====
 Any metadata that has been extracted from or added to documents can be referenced in format statements using the ''gsf:metadata'' tag. Metadata is referred to by its element name. For example, if you have provided ''dc.Title'' metadata for your documents, ''<gsf:metadata name="dc.Title"/>'' will display these values.
-If you want to display the file name for documents, ''<gsf:metadata name="Source"/>'' can be used to display them; to display the number of pages/sections in a document, use ''<gsf:metadata name='numDocs'/>'' to display the number of pages/sections in a document. //(Note that the metadata name does not include the ''ex.'' namespace. Extracted metadata is referred to without the namespace in format statements. Metadata in all other namespaces--e.g. ''dc.'', ''gs.'', ''dls.'', etc.--__does__ require the namespace, as shown in the ''dc.Title'' example above.)//

+===== Classifier Metadata =====
+Metadata for classifiers is referenced in the same way as for a document, like <gsf:metadata name="Title"/>. Classifier nodes only have a very limited set of metadata however.
+  * Title - the Title metadata gives the name of the classifier or bookshelf. One thing to note is that a bookshelf label is always stored as Title metadata, regardless of what metadata the classifier was built on.
+  * numleafdocs - this gives the number of documents underneath this part of the classifier.
